A sensor assembly includes a rectangular-shaped pressure sensor element and an electronic circuitry coupled to receive a signal from the pressure sensor element. An open-ended fluid-tight passageway of the sensor assembly conveys fluid from a portal opening of the sensor assembly to a surface of the rectangular-shaped pressure sensor element. The sensor assembly further includes a closed-ended fluid-tight passageway, at least a portion of which is fabricated from metal. The closed-ended fluid tight passageway extends from at least from the portal opening of the sensor assembly to the electronic circuitry on at least a portion of a path adjacent to the rectangular-shaped ceramic pressure sensor element. The sensor assembly includes a temperature sensor element disposed in an end of the closed-ended fluid-tight passageway. Conductive links disposed in the closed-ended fluid tight passageway electrically couple the temperature sensor element to the electronic circuitry.

Combination pressure/temperature in a compact sensor assembly

A high pressure, miniature pressure sensor has a cup-shaped housing having an open end closed by a metal substrate. A raised stress isolation pedestal portion is formed on the substrate that receives a stress isolation glass pedestal element and in turn a silicon pressure sense element, all having closely matched CTEs to minimize temperature induced stresses. A fluid passageway is formed through the substrate and glass pedestal and an O-ring is placed around the passageway on the lower side of the substrate. A flexible circuit having a slit tail formed with two lobes for receipt respectively in the housing and on the substrate allows easy access of a solder iron during assembly. Mounting flanges extend from the substrate to facilitate mounting of sensor and minimize transfer of mounting stresses to the sense element.

Pressure sensor apparatus

A switch system () for use with vehicular transmissions for providing an indication of transmission operation in which an electrically insulating ramp plate () is fixedly mounted on a face surface of an electrically conductive detent plate (). Detent plate () has a shaft receiving bore () formed in a hub () that extends from a face surface and interfits with hub () of the actuator plate. The detent plate is fixedly mounted to a rotatable shaft received in the bore of hub () and is rotatably mounted relative to actuator plate (). Ramp plate () has a plurality of openings each defined by a lifting ramp at two opposite ends and conductive leads mounted on the actuator plate, as by insert molding, extend into cut-outs formed in the actuator plate. These cut-outs are alignable with the openings in the ramp plate and the conductive leads have free ends biased toward the detent plate so that rotation of the actuator plate will selectively close or open circuits between the conductive leads and the detent plate. In an additional embodiment, a locking feature is provided for locking the switch system in a selected orientation during shipment to an OEM by using a pin () that is only partially inserted through a bore aligned with a reference feature () of the actuator plate.
